ANTIGLARE GOGGLES Filed oct.l19, 193s my/Wml ATTORN EY S Patented June14, 1938 UNITED STATES- l PATENT GFFICE 3 Claims.

This invention relates to anti-glare goggles, and its general object isto provide goggles of that character which are primarily designed foruse by drivers of motor vehicles, in. that the lenses thereof can beadjusted to eliminate the glare regardless of the direction of lighttoward the goggles and in an easy and expeditious manner, without thewearer removing the same.

A further object ofthe invention is to provide anti-glare goggles thatinclude lenses of a size to leave unoccupied space in the lens rims, toallow easy adjustment of the lenses and so that the driver can obtain anormal view of the road when desired.

Another object of the invention is to provide anti-glare goggles thatinclude temple-bars that have relatively wide portions at their juncturewith the lens rims, to act as anti-glare means.

A still further object of the invention is to provide gogglesof thecharacter set forth, that are simple in construction, inexpensive tomanufacture and extremely eiicient in use and service.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinaiter` fully described, illustrated in the accompanying drawingand specically pointed out in the appended claims. l

In describing the invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure l is a perspective view illustrating the goggles which form thesubject-matter of the present invention.

Figure 2 is a sectional view taken approximately on line 2-2 of Figurel, looking in the direction of the arrows.

Figure 3` is a sectional view taken approximately on line 3--3 of Figure1, looking in the direction of the arrows.

Figure i is a detail view showing one of the lenses, and it s retainingspring.

Figure 5 is a view of a modified form of lens Referring to the drawingin detail, and particularly to Figures l to 4 inclusive, it will benoted that myogoggles include the usual lens frame having rims l ofcircular formation, which are connected by a, noseI bridge 2 and havenose rests 3 formed thereon.

The rims are interiorly grooved about the entire circumference thereof,to provide a channel 4 to slidably receive curved edges of the lenses 5,for movement therein, as will be apparent.

The lenses 5 are shown as being of substantially semi-circularformation, in that they are provided with straight edges 6, but they maybe of other shapes provided of course the curved edge fits the curvatureof the rims l. The lenses are translucent and may be of any color,aswell as formed from any material suitable for the purpose, and due tothe senil-circular formation, it

` will be obvious that an unoccupied space l is provided, to allow forthe movement of the lenses, or the adjustment thereof to variouspositions with respect to their rims, as suggested in full and dottedlines in Figure l, and of course the unoccupied space allows the driverto obtain a normal view of the road when desired.

The lenses are not only shown as being of semi-circular formation, butare outwardly curved to provide the concave-convex formation, as will benoted upon inspection of Figure 3, and in order to hold the lenses in.adjusted positions, as well as within the rims, I employ retainers twhich in fact are semi-circular strands oi resilient wire having theirends bent inwardly toward each other as at t to contact the straightedges of the lenses at their juncture with the curved 4edges thereof, assuggested in Figure e. The retainers il are likewise mounted in thechannels t, and it will be obvious that they rotate simultaneously withthe lenses when adjusting 'the latter.

Formed on the straight edges of the lenses and preferably adjacent theends thereof, are lugs or fingers it, to facilitate the adjustment ofthe lenses, and the lugs extend forwardly from the straight edges, asclearly shown in Figure 3.

Hingedly secured to the outer sides of the rims are temple-bars li whichinclude relatively wide portions l2 at their hinged ends, which not onlystrengthen the same at their connection with therlnis, but the wideportions likewise act as anti-glare means,. in that they prevent thelight from entering the space between the head and the'rims, at theouter sides of the latter. The temple-bars terminate at their outer endsin curved portions i3 for clamping association with the head of thewearer, in the form as shown, or the portions may be curved to an extentto be disposed about the ears of the wearer, as will be apparent.

In Figure 5, I have illustrated a modified form of lens which is'similar to the form previously mentioned, with the exception that it isprovided with extensions I4 projecting laterally at the upper and lowerends of the straight edge i6. The extensions i4 make' it possible toeliminate the, retainers 8, thereby reducing the cost of manufacturingthe goggles. The extensions are relatively narrow and the outer edgesthereof follow the curvature vof the curved edge of the lenses. whiletheir inner edges are straight and disposed at right angles with respectto the straight edge I5.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several'parts, provided thatsuch changes fall within the scope of the appended claims.

What I claim is: Y

1. Anti-glare goggles comprising a, frame, including circular rims, eachhaving a groove in the inner surface thereof, translucent lenses mountedin the grooves for rotatable movement to various adjusted positions andeach lens be' ing of semi-circular formation to provide a straight edgeand to leave an unoccupied space in the rims, means to hold the lensesin adjusted positions, lugs formed on the straight edges of the lensesadjacent to the outer ends thereof and extending forwardly therefrom atright angles thereto, and said lugs providing handles to facilitate themovement of the lenses.

2. Anti-glare goggles comprising a frame includingrcircular rims, eachhaving a groove in the inner surface thereof, concavo-convex translucentlenses mounted in the grooves for rotatable movement to various adjustedpositions, each lens being of semi-circular formation to provide astraight edge and to leave an unoccupied space in the rims, lugs. formedon the lenses and providing handles to facilitate the movement thereof,and substantially semi-circular strands of resilient wire rotatablymounted in the grooves and having inwardly bent ends engaged with thestraight edges of the lenses for holding the latter in their adjustedpositions.

3. Anti-glare goggles comprising a frame including circular rims, eachhaving a groove in the inner surface thereof, semi-circular vtranslucentlenses providing inner straight edges therefor and mounted in thegrooves for rotatable movement to various adjusted positions, lugsformed on the lenses and extending at right angles from adjacent theends of the straight edges thereof to provide handles to facilitate theadjustment of the lenses, and extensions formed on the straight edges atthe ends thereof and received in the channels to aid in holding thelenses in the rims. n
